(usually transcribed as psyche): soul; breath of life, life-stuff; Homer distinguishes between a free soul as a soul of the dead, corresponding with psuche (and still regarded as an eidolon), and body souls, corresponding with thumos, noos and menos: following the Egyptian theological patterns, the Pythagoreans constituted the psuche as the reflection of the unchanging and immortal principles; from Plato onwards, psuchai are no longer regarded as eidola, phantoms or doubles of the body, but rather the human body is viewed as the perishable simulacrum of an immaterial and immortal soul; there are different degrees of soul (or different souls), therefore anything that is alive has a soul (Aristotle De anima 414b32); in Phaedrus 248b the soul is regarded as something to be a separate, self-moving and immortal entity (cf.Proclus Elements of Theology 186); Psuche is the third hupostasis of Plotinus.
